NFL Nation: 4 Downs -- AFC East

New England Patriots coach Bill Belichick has job security. His three counterparts in the AFC East? Not so much.

Rex Ryan landed a contract extension this offseason, but don't let that fool you. He will have reason to be nervous if the New York Jets miss the playoffs for the fourth consecutive season. The Buffalo Bills' 6-10 record last season wasn't ominous for Doug Marrone -- that was just his first year on the job. But with an ownership change on the horizon, a failure to improve in 2014 might not bode well for Marrone.

Then there is Joe Philbin of the Miami Dolphins. He survived a bullying scandal that took place in his locker room and on his practice field. A late-season collapse that cost Miami a playoff berth couldn't sink Philbin, not when you consider the adversity the team fought through just to be in contention. But now Philbin enters his third year, when a lot is expected of a regime. He is likely out of second chances.

The four writers who cover the division -- Rich Cimini in New York, Mike Reiss in New England, Mike Rodak in Buffalo and James Walker in Miami -- offered their insights on the AFC East hot seat and other key topics. They also polled their Twitter followers to find out if they saw the issues differently.
